Hi Marv,
> ... What fixes did you have to do to the slmodem package?
I made two changes.
============== Change 1 unsupported codec ========
The first is because the DPH-50U uses an unsupported codec. As I don't need the modem functionality, this wasn't a big concern for me.
I don't recommend taking this change.
// drivers/st7554.c, Line 1270
if (val&GPIO_MONOLITHINC) { /* st75951/2 silicon DAA codec */
USB_ERR("st7554 probe: unsupported codec st75951/2.\n");
s->codec.name = "stlc75971/2";
#if HACK_FORCE_SUCCESS_NOT_RECOMMENDED
USB_ERR("**hack**, codec not recognised, be prepared to crash soon **hack**\n");
s->codec.set_srate = stlc7550_set_srate ;
s->codec.set_format = stlc7550_set_format;
#else
goto error;
#endif
}
============== Change 2 (linking alsa on 64bit) ========
On Ubuntu 8.0.4 with an AMD 64 bit machine, the 64bit version of libasound.so is being passed to the linker when building (32bit) slmodemd with ALSA_SUPPORT=1.
// Makefile, Line 55
%-sub-dirs:
$(foreach dir,$(sub-dirs),$(MAKE) -C $(dir) $(patsubst %-sub-dirs,%,$@) && ) echo "done."
// modem/Makefile, Line 41
slmodemd modem_test:
$(CC) -lasound $(LFLAGS) -o $@ $^
//modem/Makefile, Line 34
#SUPPORT_ALSA:=1
ifdef SUPPORT_ALSA
slmodemd: -lasound
CFLAGS+= -DSUPPORT_ALSA=1
LFLAGS+= -lasound
endif
It seems the top-level makefile is expanding "-lasound" to "/usr/lib/libasound.so" instead of the 32bit version, "/usr/lib32/libasound.so"
Actually, I'm not sure of the proper fix here, as my makefile-fu is weak.
I have a fix which works locally but is incompatible with IA-32 machines. I'm happy to test an updated version if someone is willing to suggest a better fix.
Cheers,
--Chris
============ Original Message ==================
Chris,
RE: trying to do: Get ALSA to identify my DPH-50U as an *audio*
capture&playback device:
----------
To the best of my knowledge, /dev/ttySL0 virtual ports are not Sound
competent yet, though it is planned for the future.
What fixes did you have to do to the slmodem package?
It they are generally needed, the package should be updated.
The compile is OK on my system:
/slmodem-2.9.11-20080817$ ls drivers/*.ko
drivers/slamr.ko drivers/slusb.ko
